[0048] The pouring ladle of the copper rod continuous casting and rolling production line (not shown in the figure) is in communication with the output end of the third flow guide groove 30; the copper rod continuous casting and rolling production line can apply any production line on the market to produce copper rods from the front-end input copper liquid.

[0049] As a preferred embodiment of the present embodiment, the holding furnace 3 is arranged on the eccentric rotating device 4 and rotates with the rotating mechanism of the eccentric rotating device 4, and the copper liquid in the holding furnace 3 is fully stirred by the eccentric rotating device 4. The holding furnace 3 is equipped with two lances.

[0050] Specifically referring to Figure 2 As a preferred embodiment of the present embodiment, the top surface of the secondary refining furnace 2 is an assembled top cover 21, and a plurality of through holes 22 are arranged on the top cover 21 at intervals. In the present embodiment, four through holes 22 are arranged, and each through hole is a structure of a large hole surrounding a small hole, with a large hole diameter of 300 mm and a small hole diameter of 200 mm.

[0051] Specifically referring to Figure 3 The through holes 22 can also be arranged on the side wall of the refining furnace 2. A transverse moving mechanism 5 is arranged beside the refining furnace 2, and a plurality of air pipes 50 corresponding to the number of through holes 22 are arranged horizontally on the transverse moving mechanism 5. The left ends of the two air pipes 50 are respectively matched with two through holes 22. The right ends of the air pipes 50 are used to communicate with a refining gas pipeline (not shown in the figure). The refining gas pipeline is used to input refining gas into the air pipes 50, such as air, natural gas, oxygen, hydrogen, nitrogen, etc. The refining gas is used to oxidize and reduce the copper liquid to realize refining and slag removal. In the present embodiment, the air pipes 50 are arranged on the side of the refining furnace 2, and the refining gas is injected into the refining furnace in the form of side blowing, which can make the contact area of the copper liquid and the refining gas larger and the reaction more sufficient, so that the refining of the copper liquid is more uniform.

[0052] Specifically referring to Figure 3 As a preferred embodiment of the present embodiment, the transverse moving mechanism 5 includes a frame 51 and an electric control telescopic rod 52 fixedly arranged on the frame 51. In the present embodiment, two electric control telescopic rods 52 are arranged on both sides of the frame 51. An operation box is arranged at the bottom of the frame 51, and a power supply and a control panel of the electric control telescopic rod 52 are arranged in the operation box.

A plurality of fixing holes are arranged on the air pipe connecting plate 53, and each air pipe 50 is respectively sleeved with each fixing hole.

[0053] As a preferred embodiment of the present embodiment, the front of the secondary refining furnace 2 is provided with an operating port 23 and a slagging port 24, and the rear is provided with a flue communication port 25. The operating port 23 is used for putting refining materials such as slagging agents, and the slagging port 24 is used for removing waste slag generated in the refining process. The flue communication port 25 is used for connecting the flue. The top of the flue communication port 25 is flush with the top of the secondary refining furnace 2. The flue of the prior art refining furnace is raised and then leveled and then folded down. The flue communication port 25 of the present embodiment is directly leveled out from the rear of the refining furnace, which saves the raised section. When the original refining furnace blows oxygen to form slag, impurities are easily attached to the raised position of the flue. When reduced, the impurities fall back into the copper liquid, resulting in an increase in impurity data. The present embodiment solves this problem.

[0054] The present embodiment cooperates two primary refining furnaces 1 with two secondary refining furnaces 2. The two primary refining furnaces 1 can alternately input scrap copper materials and alternately perform rough refining of scrap copper, achieving 24-hour uninterrupted production. The refined copper liquid can flow to two refining furnaces 2 for refining. When the copper liquid flowing into the secondary refining furnace 2 reaches a certain specification, the valve of the first flow guide groove 10 can be controlled to make the copper liquid flow to another secondary refining furnace 2, so that the two secondary refining furnaces 2 alternately input refining, achieving 24-hour uninterrupted copper liquid refining. The refined copper liquid flows to the copper rod continuous casting and rolling production line through the holding furnace 3, and the copper rod is made.

[0055] The present embodiment sets the primary refining furnace 1, the secondary refining furnace 2 and the holding furnace 3 with height difference. The copper liquid is turned upside down during the process of flowing from the primary refining furnace 1 to the holding furnace 3, which is beneficial to the full mixing and deslagging of the copper liquid.

[0056] For details, see Figures 4-7 As a preferred embodiment of the present embodiment, the first flow guide groove 10 or the second flow guide groove 20 or the third flow guide groove 30 includes a main flow channel 61 extending downwardly and obliquely and a plurality of auxiliary flow channels 62. The auxiliary flow channels 62 are arranged in two rows on both sides of the main flow channel 61. The upper / lower end of the auxiliary flow channel 62 on one side is connected to the middle of the auxiliary flow channel 62 on the other side through a communication groove 63.

[0057] Under normal circumstances, the copper liquid flows in the main flow channel 61, as shown in Figure 5When a blockage occurs in a localized area of ​​the main channel 61, the flow rate decreases. Since the top of the main channel 61 is hollowed out and tilted, the reduced flow rate can easily cause the water level at the blockage location to surge and overflow. Therefore, a secondary channel is set up next to the main channel 61. When a blockage occurs, the copper liquid water level rises and flows through the connecting groove 63 into the nearest secondary channel 62. Then, it flows back into the main channel 61 through the connecting groove 63 at the lower end of the secondary channel 62, thus bypassing the blockage location. Each connecting groove 63 is equipped with a liquid level sensor 64 on its top wall. The liquid level sensor 64 determines whether there is copper liquid flowing in the corresponding connecting groove 63.

[0058] like Figure 6 As shown, the fixed track 72 is relatively fixed and its trajectory is consistent with that of the main channel 61. A groove is formed in the fixed track 72 along its trajectory direction, and a rack 74 consistent with its trajectory is installed on the bottom wall of the groove. A motor 73 is installed in the movable seat 71. A coaxial gear 75 and a first roller are installed at the output end of the motor 73. The gear 75 meshes with the rack 74, and the first roller rolls in the groove. A second roller that rolls in the groove is also installed on the movable seat 71. The motor 73 drives the gear 75 to rotate. The rotation of the gear 75 and the meshing of the rack 74 drive the movable seat 71 to move relative to the fixed track 72. During this process, the first roller and the second roller play an auxiliary role.

[0059] like Figure 7 As shown, the rotary lifting assembly 81 and the waste bin 84 are installed on the top of the movable seat 71. The rotary lifting assembly 81 includes a rotary assembly and a lifting assembly, which have rotation and lifting functions. A horizontally set crossbeam 82 is installed at the upward output end of the rotary lifting assembly 81, and a retrieval cage 83 is installed at the bottom of the other end of the crossbeam 82 away from the rotary lifting assembly 81.

[0060] The outer contour of the retrieval cage 83 is adapted to the cross-section of the main channel 61; the retrieval cage 83 has an "L" shaped structure and is provided with comb grooves; a comb block 84 is fixed in the middle of the inner cavity of the waste box 84, the comb block 84 is adapted to the comb grooves of the retrieval cage 83, and the top wall of the comb block 84 is inclined downward. Position sensors are evenly installed along the length of the fixed track 72, and each position sensor corresponds to a position of a secondary channel 62.

[0061] Working principle: When the main channel 61 is blocked, the copper liquid level in the main channel 61 rises to the nearest flow channel 63. The liquid level sensor 64 in the flow channel 63 detects the rise in the liquid level in the flow channel 63 and sends a signal to the controller (PLC or microcontroller). After receiving the signal, the controller controls the moving device 7 to drive the unblocking mechanism 8 to move to the blockage position. The moving device 7 can accurately move to the blockage position by cooperating with the corresponding position sensor.

[0062] After the rotation of the rotation and lifting assembly 81, the lifting of the fishing cage 83 is moved to the main flow channel 61, and since the fishing cage 83 is provided with the comb tooth slot, the copper liquid flow is not affected too much; then the moving device 7 drives the direction of the unblocking mechanism 8 to move (against the direction of the copper liquid flow), so that the fishing cage 83 is inclined upward in the main flow channel 61, thereby shoveling the blocking piece in the main flow channel 61, and the "L" type structure of the fishing cage 8 can accommodate the blocking piece in the process;

[0063] After the rotation of the rotation and lifting assembly 81, the lifting of the fishing cage 83 is moved to the main flow channel 61, and since the fishing cage 83 is provided with the comb tooth slot, the copper liquid flow is not affected too much; then the moving device 7 drives the direction of the unblocking mechanism 8 to move (against the direction of the copper liquid flow), so that the fishing cage 83 is inclined upward in the main flow channel 61, thereby shoveling the blocking piece in the main flow channel 61, and the "L" type structure of the fishing cage 8 can accommodate the blocking piece in the process;

[0064] The above is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the present application.
